Mylab, I am a bit of a coward when it comes to reading dark stuff and, if I'm aware that an author is well-known for writing 'disturbing' books I tend to shy away from them.
Off-hand I can't think of any title of the kind you describe that I might have read, though I'm sure there must be one or two that I may have picked up by mistake. If I remember it/them I'll get back to you.
Sorry to be so vague.

I felt that way when I read "Fall On Your Knees" years ago. I was utterly repulsed and turned off. (Another dysfunctional family novel). I tried to read Gillian Flynn's "Gone Girl" but found the little I read creepy, so never got into it.

I understand the avoidance of dark subjects - I read "The Road" the year it came out - it was so disturbing that I skipped the book club discussion, wouldn't watch the movie when my husband found it on the movie channel. I reacted the same way to my book club's selection of B*****d Out Of Carolina - I completely quit going to the book club for about six months, I was worn out.

(******** is a child born out of wedlock as the forum wont accept the spelling of the actual word.)

Both were so well written, certainly, but so hopeless that I was off any reading subject matter which was of deeply dark subject matters for many years

So, I'm surprised I am so attracted to Flynn's books- it must be her writing style or her ability to deal with her subject matter in an unflinching manner. Who knows?
She is a formidable talent but were I a writer I would consider myself truly cursed if her's were the stories that I had within me demanding to be given birth.
I can't imagine working on those subjects every day for however many years it takes to complete her books.

I felt the same way about Gone Girl, it became darker and darker but I couldn't stop reading. Thankfully, it wasn't as gruesome as some other books I've read.

I usually totally avoid dark stories -- I had to read Emma Donoghue's ROOM for my book group and while I could admire what she did and the way she wrote it and I do think she's vastly talented -- god, I wish I'd never read it. Blech.

As for The Road, I told my book group that was the one book I flat-out would not read if they chose it. I skimmed a page or two once at the bookstore and that was more than enough.

I do rather like bittersweet books but avoid the out and out dark and dismal side of literature. I can handle sadness, even unhappy endings, but don't want to read about despair or horror. There is already more of that in the real world than I can easily tolerate. I don't want to fill my mind with even more of it. My imagination is too vivid, and it seems too real to me.
